Question

tan(0)=15/8 What does this mean?

Answer 1

i think it must mean that
\[\tan(\theta)=\frac{15}{8}\] because
\[\tan(0)=0\]

Answer 2

Yeah right

Answer 3

there is a picture where
\[\tan(\theta)=\frac{15}{8}\] if you want the hypotenuse of the triangles solve
\[h=\sqrt{15^2+8^2}=\sqrt{225+64}=\sqrt{289}=17\]
